Case study of BMW 3 Series upgraded SAVANINI calipers
Customer review:The original factory calipers really have a braking effect only when you press them all the way down. After upgrading to the six-piston calipers, I always felt that it was a bit lacking. I thought, why not upgrade the rear wheels as well? The caliper kit with six in the front and four in the rear is quite reasonably priced and has a very good appearance. When I got it, I found it was really amazing and the feel was also better
